MCS is the UK’s quality mark for renewable energy systems like solar panels and heat pumps. We set the standards you should always expect from an MCS certified installer and the products they use, whether your installation is going into your home or business.

Because at our heart we’re here to support you – providing protection and peace of mind as you make the switch to ‘home-grown energy’.

So, if you are thinking about installing any form of renewable energy, start with us.

MCS is a mark of quality which demonstrates adherence to recognised industry standards; highlighting quality, competency and compliance. We certify low-carbon products and installations used to produce electricity and heat from renewable sources. MCS sets out what consumers should expect at every stage of the installation process. 

Our mission is to give people confidence in low-carbon energy technology by defining, maintaining and improving quality.

There are a range of grants and incentives to provide financial support for installing renewable technologies. To see if your installation is eligible for financial support, take a look at our grants and incentives page. 

MCS certification is a requirement for accessing many UK government incentives. Before going ahead with your renewable installation, it’s important to check that your installer is MCS certified and uses MCS certified products.
